Photo Locations: Palo Duro Canyon Texas
 From Wikipedia: Palo Duro Canyon is a canyon system of the Caprock Escarpment in the Panhandle of Texas. As the second largest canyon in the United States, it is roughly 193 km (120 mi) long and has an average width of 10 km (6.2 mi), but reaches a width of 32 km (20 mi) at places. Its depth is around 250 m (820 ft) but in some locations it can increase up to 304 m (997 ft). Palo Duro Canyon has been named "The Grand Canyon of Texas," both for its size and for the dramatic geological features, including the multicolored layers of rock and steep mesa walls similar to those in the Grand Canyon.
The canyon was formed by the Prairie Dog Town Fork Red River which initially winds along the level surface of the Llano Estacado of West Texas then suddenly and dramatically runs off the Caprock Escarpment. Water erosion over the millennia has shaped the canyon's geological formations.
Notable canyon formations include caves and hoodoos. One of the best known and the major signature feature of the canyon is the Lighthouse Peak. A multi-use six-mile round trip loop trail is dedicated to the formation. The middle portion of the trail can be hot with little shade, and hikers should take plenty of water.
The painter Georgia O'Keeffe who lived in nearby Amarillo and Canyon early in the 20th century, wrote of the Palo Duro: "It is a burning, seething cauldron, filled with dramatic light and color."
